After treatment, a dense and uniform phosphate film is formed on the surface of the workpiece, which is widely used in the drawing of all kinds of steel pipes and the lubrication of stamping parts. The phosphating solution has the advantages of low treatment temperature, fast film formation, easy control and low cost.
1、 Main technical specifications
2、 Main features
1. In the process of use, the accelerator should be added separately, and the same agent should be used in the tank and the addition, so the operation is simple and the management is convenient.
2. This product has good stability, less sediment and long service life.
3. The phosphating film has dense crystal, gray and no ash, which can enhance the lubricity of steel pipe and reduce the comprehensive cost.
3、 Application method and process parameters
1. Treatment process: rust removal → neutralization → water washing → phosphating → water washing → wetting agent
2. The phosphating solution was prepared into 8% working solution, and neutralizer and accelerator were added per ton to make it dissolve and stir evenly.
3. Process parameters:
FA: 1.5 ~ 2.5pt, treatment temperature: 55 ~ 65 ℃
TA: 24 ～ 34pt, treatment time: 5 ～ 10min, accelerator AC: 2 ～ 5pt
4. As the concentration changes continuously in the continuous treatment process, it is necessary to measure the concentration of each index regularly to keep each index within the specified process concentration range.
4、 Packaging, storage and transportation
30kg plastic barrel packaging, storage and transportation temperature not less than 0 ℃.
